Be it known that I, WILLIAM W. Bnoeay a citizen of the United States ofAmerica, rnd a resident of Springfield, in the county of I'Iampden andState of Massacl'iusetts, have invented certain new and usefulImprovements in Flushing Apparatus for \Vater (,lloset Bowls, of whichthe following is a full, clear, and exact description. l

This invention relates to flushing mechan ism for water-closet bowls,and more espe-\ cially to that class thereof in which the bowl compriseswhat is generally known as a rim r spray and also a trap or seal stream;and it has for one of its objects the provision of a device wherebywater is supplied to either the rim or to the trap in succession, so asto concentrate its force into one particular part of the bowl at any onetime.

My invention has, furthermore, for its object the provision of adistributing-valve for admittil'ig and shutting olf the water-supply foreither the rim or trap in regular order and alternately and finallyadmitting water to both the rim and trap simultaneously.

My invention has, furthern'iore, for its object the combination, withthe water-supply pipe, of a balanced shut-off valve interposed betweenthe source of water-supply and distributing-valve and comprising a pairof independently-(n'ierable valve-disks of diflerent areas, the smallerdisk being operable by a handle to relieve the pressure on the maindisk, which controls the admission of a large body of water to thechamber of the distrib uting-valve.

Further objects of my invention will be found in the particularcoi'istruction and organization of some of the components of the device,as illustrated in the accompanying drawings, in which similar charactersdenote similar parts, and in which Figure 1 is a vertical centralsection of my IIUPI'OVOd mechanism applied to a bowl of ordinaryconstruction and taken on line 1 1. Fig. 2. Fig. 2 is a section on line2 2 of Fig.

tion on lines 5 5 of Fig. 1. Fig. 6 represents a section on line 6 6,Fig. 1. Fig. 7 isacentral section of an ordinary bowl and illustrates myimproved mechanism applied thereto. and Fig. 8 shows a fragmentary viewof a bowl as especially adapted for my improved device.

Briefly stated, my improved device comprises a main valve for cuttingoff the watersupply, this alve being of ample capacity to admit a largebody of water under pressure, and inasn'iueh as considerable power wouldbe required to raise this valve from its seat I provide in the mainvalve a small valve of greatly-reduced area, which maybe easily operatedby hand, and thus relieve the pressure on the main valve, whichsubsequently raised to admit a full supply to a movabledistrilmting-valve having a series of ports and bridges which during itsreturn movement will admit water into the rim and the trap alternatelyand finally to both simultaneously, while the main valve graduallycloses during the return movement of the distributing-valve.

In the drawings, 10 denotes the water-supply pipe, which may beconnected directly with a main or with a tank, as desired. Secured tothe end of the pipe 10 is my improved liushingdevice, comprising acasing II, which is divided into a series of preferably superposedchambers ll. 13, and 14, respectively. The reeeiviug-chamber 12 isformed cylindrical and contains the main cut-oil valve, consisting of apiston 15, having a neck portion 16 and a valve-disk 17, adapted toclose the passage 18, leading to the distributingvalve chamber 13. Theweb of the piston 15 has an aperture 19, through which water may enterinto the closed portion of the chamber 12 and as controlled by anadjusting-screw 2.0, as will be readily understood. The neck portion 16is tubular, and its uper opening is normally closed by a primaryrelief-valve 21, the stem 22 of which maybe guided by a bar or yoke 23,secured to the piston 15 in any convenient manner. Inasmuch as the topof the chamber .12 is tightly closed as, for instance, by a cover 2 l itfollows that considerable pressure is brought to bear upon the piston ormain valve 17, and therefore I prefer to manipulate the smallervalve-disk 21 by any suitable mechanism or in the manner shown in Fig.1, in which the lower end of the stem 22 carries a pin 2% in engagementwith the bifurcated or slotted end of a lever 25, mounted on ar0ck-shaft 26, which may be journaled in bearings 27 28 of the casing 11and the outer end of which may be bent to constitute a lever 29, havinga weighted handle 30.

From the foregoing it will be seen that when the handle 30 is raised theprimary valve 21 will be lifted from its seat until it strikes the underside of the yoke 23, at which time the water above the piston 15 and thevalve 21 will be free to pass through the tubular neck 16, thusrelieving the pressure above the piston 15, and consequently render--..

ing it easy to continue the upward movement of the handle 30, andthereby raise the piston 15 bodily, and with it the main valve 17. asseen in Fig. 3. \Vater is now directly admitted from the supply-pipe 10into the distributing-valve chamber 13, where it is conducted to the rimor the trap portion of the bowl, according to the position of thedistributing-valve. This valve consists in the preferred form thereofshown of a segmental shell, consisting, preferably, of a series of ports32 33 and bridges or solid portions 34:

35 36, adapted to close an aperture 37, leading into the lowermostchamber lat, and also the mouth of a tube 38, connected with the rim ofthe bowl. The segmental shell is provided with trunnion-arms 39,journaled for oscillation in hubs il of the casing 11 and its side cover12, respectively, said arms having extensions #13, engaged bylaterally-projecting pins 44, carried by the valve-actuator 25, abovementioned, so that when the handle 30 is raised the main valve will beraised, and the distributing-valve will be simultaneously moved to thepositio 1 shown in Fig. 3.

Before proceeding with the particular operation of thedistributing-valve it may be of benefit to explain the connectionbetween my improved flushingdevice and the bowl, an ori dinary form ofwhich is illustrated in the drawings, excepting Fig. 8. Referring moreespecially to Fig. 7, the bowl B has near its top an annular chamber 1*in communication with the water-inlet chamber or by a passage 1* andhaving a series of perforations p for directing the spray against theinside of the bowl. which is provided with the usual trap T, soil-pipeS, and also the trap-cleaning conduit which leads directly from thechamber 0/) into the bottom of the bowl B, as indicated by dotted lines.It is therefore evident that water conducted into the chamber we couldenter the rim and the trap at the same time; but since it is oneparticular object of my invention to distinctly separate the rim fromthe trap, and so that the distributing-valve may become instrumental indirecting the flow veaess l of water into these channels separately,means are provided whereby the rim-channel "r is j disconnected from thechamber w, as follows:

ln screw-threaded engagement with the easing 11 and entering the chamber1% thereof is a thimble 45, having a flange 46 and carrying a ring 4:?and a nut 48 for compressing I a packing-ring 49 to contact tightly withthe Will of the chamber in. The thimble is also provided with aconduit-tube 50, which is curved to enter the passage r and has packin g51 for completely stopping all communication between the rim r and thechamber 0 Tile upper end of the tube is flaring to receive apacking-ring 52 to form a tight union between the tubes 50 and 38. Henceit wilL bis seen that water passing through the tube can only enter therim 1, while the water eir ering the chamber 14. can pass through thethimble a5 into the chamber 20 and thence only into the trap-conduit 6.Of course it is evident that these conditions may be reversed. so as toconnect the pipe 38 with the channel t. and the chamber 10 may remain incommunication with the rim-channel r, if so preferred.

In Fig. 8 the construction of the bowl B is especially adapted for myimproved flushing 1 device, the tube 50 being supplanted by a conduit50, constituting a part of the bowl, and isolating the rim-channel rfrom the channel on in the same manner as above described.

Referring now again to the distributingvalve, as shown in Fig. 3, itwill be seen that the tube 38 is closed by the bridge 31 and that waterfrom the supply-pipe 10 is passing through the port 32 into the chamber10, through the thimble 45, into the trap-conduit 6, thus washing outthe trap T and dislodging all sediment in the bottom of the bowl anddischarging the same into the soil-pipe S. Consequently the water-levelin the bowl will gradually fall until the valve-shell has been returnedby the gravitating handle 30 suliiciently to bring the bridge 35 overthe port 10 of the chamber 7/; and simultaneously establishing a flow ofwater under pressure into the tube 38, thus flushing the rim only. Icontinuation of the valve-shell movement will again admit water into thechamber o through port 33, while the bridge 35 closes the tube 38 untilfinally the valve-shell has returned to its normal position, (shown inFig. 1,) in which both the tube 38 and the chamber 7!) are in openconnection with the distributingvalve chamber 13 and drain the same, itbeing of course evident that the water-supply has been completely shutoff by virtue of the valves 21 and 17 reseating themselves, as seen inFig. 1. The speed with which the distributing-valve returns to normaldepends, of course, upon the weight of the gravitating parts of myimproved device and upon the freedom with which water may pass throughthe aperture 19 in the valve-piston, inasmuch l l l as the valve 21 willbe closed by the weighted handle 30 immediately when the latter isreleased, the piston 15 then descending also, but not faster than watercan enter the chamber 12 above the piston 15 and as may be regulated asdesired by the regulating or adjusting screw 20.

Many changes may be made in the construction and organization shown inthe drawings, and it should be distinctly understood that the entiredevice may operate in other than vertical position, so that I do notlimit my invention to gravitative elements as described.
